IMPROVEMENT IN SUBMERG-ED PUMPS.

The Schedule referred to in these Letters Patent and making part of the same.

Tov all whom fit 'may concern Be it known that I, PERRIN H. CARDWELL, of Knoxville, in the county of Knox, and State of Tennessee, have invented a new and improved Submerged Pump; and l do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making a part ot' this specication, in which my invention is represented inlongitudinal vertical section.

In this invention, the pump is so constructed that it operates to produce a constant, steady flow of water toany desired height, with the greatest possible economy of power, and lnay be set in any position, and worked from .any distance, by means of a cord and pulleys.

This pump is'constrncted with two cylinders, A A', in which work plungers B B', the rods of which are connected by a vibrating beam, in such a manner that when one plunger is going down, the other is rising.

Between the cylinders is a chamber, C, connected with each cylinder on both sides of the plunger, and also connected with the discharge-pipe D.

Each cylinder is constructed with a supply-port, e c', at its lower end, and another, i t,"at its upper end, all of them being provided with ball-valves, that seat downward. i

Each cylinder is also provided with an exhaust m fm', at its lower end, connected with chamber C by a pipe c e', and also one, n n', at its upper end, leading directly into chamber C. All theseexhausts are closed by ball-valves, seating downward.

The plunger-rods R R pass through -guides G G, which prevent them from rocking, as they move up and down.

By means of connecting-rods P P', they are attached to inwerking-beam, F, which gives them au alternating motion relatively to each other. v

The ends of the working-beam E, by means of a cord, wire, or chain, S S, running over suitable pulleys, to give them the proper direction, may be connected with a rocking'- beam, H, worked by a lever, I, or other suit-able means, and if the lever is employed, it may be strengthened by a brace, J.

The well may be situated in the field at a distance from the house, and the beam H, with its operatingdevice in the house, if desired, the delivery-pipe, D, running from the well to the house, whereby water can be obtained from'the well, at any distance, and, at whatever' direction or inclination from the house the well may be, without the necessity of going out of doors for the purpose.

The whole apparatus, consisting of the cylinders, rods R It' l? P', and working-beam F, will occupy but 'a few inches, and may be under water in any well,

and as the conuecting-wires S S will be cheap and light, the whole instrument can be put in working- 0pei-ation at little expense, and worked from a great 'fall vertically, or at an easy incline, thc cylinders and pipe D may lie at any inclination in the well that shall be most convenient.

lo effect this, I may, for some wells, be obliged to elongate my valve-chambers, and bend or curve the passages leading from them to the cylinders and cha-mber C.

The whole device being intended to operate in the manner and for the purpose above set forth, the operation of the particular parts, whereby the action of the beam F-forccs the water through pipe D, from the well to the house, may be explained as follows:

Vhen plunger B descends, it closes valves n andc, and opens valves t' and m, forcing the water out of the lower end of cylinder A into chamber C, through exhaust m and pipe c, and filling the upper part of the cylinder, through supply-port i. At the same time plunger B is rising in cylinder A', and is forcing the water above it into chamber C, through exhaust n', and drawing water into the lower end ot' the cylinder from the well, through supply-port e, the ports e and t' being open, and the port t" and rn.' being' closed. Thus, two streams of water are entering chamber C, one from the bottom of cylinder A, through pipe c, and one from the top of cylinder A', through port \Vhen the motion of the brake is reversed, the action of the plungers and valves is reversed, and the water is forced into chamber O, through pipe c' and exhaust n. Thus a steady, constant ow of water is produced, the plungers' throwing the water both from above and below them, and all the power applied to the brake being utilized to its fullest extent.

This pump is simple and cheap in construction, and can be operated with about half the power applied to the old-fashioned pump, 'besides being capable of adaptation to the purpose of drawing water, without going near the well, as above set forth.

Having thus described my invention,

What I claim as new, and desire to secure by LettersPatent, is-

The arrangement, with the cylinders A A', having supply-ports e e t t', and exhausts on m nn', of the pipes c c and chamber C, all the said parts being coustructed and combined so as to operate together, substantially in the manner and for the purposes set forth.
